Abstract
A thrust damping bearing on the upper and the lower plane of the agricultural use tricycle steering mast of the utility model comprises a cover board (1), a damping ring (2), a base (3) and a shell (4). The damping ring (2) is arranged between the cover board and the base. The utility model has a reasonable structure, and the working principle of the existing thrust ball bearing point and line contact is changed into the working principle of thrust surface contact, thus increasing the wearing property and stability of the thrust bearing, and improving the bearing capacity of the utility model. As the damping ring is made from polymer antifriction alloy material, and has self-lubricating property, thereby achieving the objective of single-time oil charging, lubricating for life, and avoding the defects that the service life and the service performance of the bearing can be influenced by the rain and dust erosion. Because the damping ring also has secondary vibration damping and good shock absorption functions, the utility model has good sense of direction under steam, thus the motocycle wander can be reduced, and ensuring the driving security. The utility model also has the advantages that the assembly is convenient and fast, no side-slipping phenomena is produced, and the partial radial load can be beared.
Description
Affiliated technical field
The utility model belongs to technical field of bearings, and what relate generally to is the upper and lower plane of a kind of agricultural tricycle direction post thrust damping bearing.
Background technique
At present, the upper and lower plane thrust damping bearing of agricultural tricycle direction post use still is traditional ball thrust bearing basically.Because the working principle of this ball bearing is point, line contact, thus work to touch face little, during running at high speed, understand poor because of directional stability, be difficult to factor such as control and influence Security.And a little less than its bearing capacity,, cause damage of bearings easily when load is super when negative.Because sealing is poor, disposable grease-added back just can't be refueled again during installation, causes bearing in use for some time because of oil starvation forms dry grinding, has quickened the damage of bearing, and the serious corrosion bearing of immersion meeting of dust, rainwater, influences its working life.In addition, because shell is gone up in design and bearing together rotates, thereby shell is easy to wear, leaks thereby produce lubricating grease, causes bearing easy-to-rust, damage.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes the upper and lower plane of a kind of agricultural tricycle direction post thrust damping bearing, to overcome above-mentioned defective, improves the working life and the usability of bearing, and can bear the branch radial load.
For achieving the above object, the utility model is achieved through the following technical solutions: it is made up of cover plate, damping ring, base and shell, and damping ring is arranged between cover plate and the base, and cover plate, damping ring and base are combined into one by shell.
The utility model is novel, rational in infrastructure.Because its working principle that will have thrust ball bearing point, line contact now is changed into the working principle of thrust face contact, thereby has increased the serviceability and the stability of thrust-bearing, improves its bearing capacity.After tested, its bearing capacity is three times of ball bearing.Because its damping ring of selecting for use adopts macromolecule antifriction alloy material, and has self-lubricating function, thereby reach disposable oiling, lifelong lubricated purpose.Avoided influencing the working life of bearing and the drawback of usability because of the erosion of rainwater, dust.Because damping ring also has the function of secondary vibration damping and good absorption impact force, thereby sense of direction is good under steam, has alleviated the yaw of locomotive, has guaranteed traveling security.Its secondary vibration-damping function under the relatively poor situation of road conditions, also plays and improves the tire function in working life.The utility model also has quick and easy for installation, no sideslip phenomenon and produces the function that can bear the part radial load.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure, 1, cover plate, 2, damping ring, 3, base, 4, shell.
Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model;
As shown in the figure, present embodiment is made up of cover plate 1, damping ring 2, base 3 and shell 4.Damping ring 2 adopts macromolecule antifriction alloy material, and it is arranged between cover plate 1 and the base 3, is the planar friction contact structures with cover plate 1 with contacting of base 3, by shell 4 cover plate 1, damping ring 2 and base 3 is combined into one.For preventing that the phenomenon of breakking away from appearring in bearing in use, the internal ring wall of loam cake 1 is designed to downwards the slightly baffle ring structure of extension, the internal ring wall of base 3 is designed to upwards the slightly baffle ring structure of extension, being used of this two grades of ring structures promptly played and prevented that bearing from producing and break away, and the effect that can bear the part radial load.Be ease of assembly, shell 4 can be designed to integrative-structure with cover plate 1 or base 3.In addition, present embodiment in use, under the effect of axial force, shell 4 does not rotate, thereby has avoided the wearing and tearing of shell, the working life of effectively having improved bearing.
Claims (3)
1, the upper and lower plane of a kind of agricultural tricycle direction post thrust damping bearing, comprise cover plate (1), base (3) and shell (4), it is characterized in that: also have damping ring (2), this damping ring (2) is arranged between described cover plate (1) and the base (3), by described shell (4) it is combined into one.
2, the upper and lower plane of agricultural tricycle direction post according to claim 1 thrust damping bearing is characterized in that: described cover plate (1) internal ring wall is designed to the baffle ring structure of extension slightly downwards; Base (3) internal ring wall is designed to slightly upwardly extending baffle ring structure.
3, the upper and lower plane of agricultural tricycle direction post according to claim 1 and 2 thrust damping bearing is characterized in that: described shell (4) and cover plate (1) or base (3) are for being wholely set.
